摘　　要：武汉市S污水处理厂已建规模为35万m^(3)/d,规划规模为60万m^(3)/d,扩建规模为10万m^(3)/d,出水标准高于《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准。厂内有多套处理工艺、多处进水入口和排放出口,改造难度较大。经论证,扩建工程选用地下式构筑物,最大限度节约现有用地,并为远期扩建预留条件。工艺流程采用“多级预处理+改良AAO生化池+膜生物反应器(MBR)池+次氯酸钠接触消毒”,运行至今出水稳定达标。S污水处理厂是武汉市唯一一座兼有地上式及地下式处理构筑物的污水厂,文章总结了污水厂地下式扩建的设计思路、设计参数和设计经验,作为同类污水厂改造的参考。S wastewater treatment plant(WWTP)in Wuhan City with capacity of 350000 m^(3)/d,whose planning capacity is 600000 m^(3)/d,is designed to be expended on a scale of 100000 m^(3)/d.The effluent standard is higher than the first class A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).Due to several sets of treatment process,several raw water intakes and discharge outlets in the WWTP,modification has been complicated.After comparison,underground structure is selected in expansion project,in order to save the existing land to the maximum extent and reserve conditions for long-term expansion.The process adopts"multi-stage pre-treatment+modified AAO+MBR+disinfection by sodium hypochlorite",and the effluent quality meets the standard steadily.S WWTP is the only WWTP with both above-ground and underground treatment structures in Wuhan City.This paper has summarized the design ideas,design parameters and design experience of the underground extension of the WWTP,to provide a reference for the modification of similar WWTPs.
